- Most functions that used to return `~[~str]` for a list of substrings got turned into iterators over `&str` slices
- Some cleanup of apis, docs and code layout
The basic problem was that vtables were not being resolved. The fix uncovered another issue, which was that the syntax extensions were not creating method calls properly and were relying on outdated code in typeck, so I fixed that too.
Resolves issues #3888, #4036, #4492.

and from typeck, which is verboten. We are supposed to write inference results
into the FnCtxt and then these get copied over in writeback. Add assertions
that no inference by-products are added to this table.

This currently requires workarounds for the borrow checker not being flow-sensitive for `LinearMap` and `TrieMap`, but it can already be expressed for `TreeMap` and `SmallIntMap` without that.
Kills some warnings, and implements str::each_char_reverse so that it actually iterates. The test case wasn't detecting a failure, since the loop body was never executed.
`let v = [24, ..1000];` now more or less emits the same IR as:
```Rust
let mut i = 0;
while i < 1000 {
v[i] = 24;
i += 1;
}
```
LLVM will still turn it into a memset if possible with optimization on.
The reasoning for doing it this way is that it's much easier to transition method-by-method to the `Map` API than trying to do the migration all at once.
I found an issue unrelated to my changes in one of the run-fail tests - if it uses `LinearMap`, it still fails but exits with 0. I xfailed it for now and opened [an issue](https://github.com/mozilla/rust/issues/5512), because it's not caused by these changes.

There are a lot of commits here, but not all that much substance. Mostly just refactoring.
I started sketching out the beginnings of a very simple I/O API in `core::rt::io` that represents I/O streams as a single `Stream` trait instead of `Reader` / `Writer` pairs. This seems to be the more common pattern (at least this is how the .NET BCL does it) and it seems to me that separate readers and writers would make duplex streams very awkward. Regardless, I don't intend to go very far down the I/O API design road without some mailing list discussion.
I've also started on the uv bindings for file I/O but haven't gotten very far.
Also hooked up the new scheduler to `rust_start` and the compiletest driver. 70% of run-pass test cases already pass, but I wouldn't read too much into that.
I also split the direct, low-level uv bindings in two so that the scheduler can have its own set, leaving `std::net` on its own.
As per #2521. Inlining seems to improve performance slightly:

```Rust
fn foo() -> int {
int::from_str(~"28098").unwrap()
}
fn main() {
for 1000000.times {
foo();
foo();
foo();
foo();
foo();
}
}
```
All run on:
Linux 3.2.0-0.bpo.4-amd64 #1 SMP Debian 3.2.35-2~bpo60+1 x86_64 GNU/Linux
The MIPS and ARM bits I didn't inline since I'm not as familiar with them and I also can't test them. All green on try.
